King Col is a very steep mess of terrain with hard packed dirt scattered along crumbly granite faces. There are small rocks that make the slope even more unstable to stand on. Every step down is an exercise in how close you’re willing to come to being smashed into sausage as you tumble down the slope.

Pro Tip: We do NOT recommend using King Col without technical gear despite its "Class 2" rating by Secor due the extremely steep, narrow, and loose upper chute on the north side. We won't make this mistake twice! We'll share several pictures here since we were unable to find any when considering the route for our trip. Since then, we found Roger Lilly's pics which give a better view of the top, steep section (the snow wasn't all the way across on our trip) where we were too busy surviving to snap any shots. There's now also a detailed King Col post on High Sierra Topix, and we wholeheartedly agree with the sentiment expressed there ("every step down is an exercise in how close you're willing to come to being smashed into sausage as you tumble down the slope"). In summary, King Col is generally to be avoided.
